san*_*nic 5 python django admin
我正在写我的第一个Django应用程序.我有以下数据库模型:
class Person(models.Model):
first_name = models.CharField(max_length = 100)
last_name = models.CharField(max_length = 100)
class InformationType(models.Model):
name = models.CharField(max_length = 100)
class Information(models.Model):
person = models.ForeignKey(Person)
info_type = models.ForeignKey(InformationType)
info = models.CharField(max_length = 200)

我想通过按类型拆分信息模型并动态地创建Django Admin(类PersonAdmin(ModelAdmin))中的多个内联.此外,我想从用户界面隐藏(排除)字段'info_type'并自动用相应的值填充它.
我可以使用'info_type'过滤的'信息'数据动态创建内联,但在UI中隐藏此字段会使其在保存时为空.
我该怎么做?是否可以制作隐藏的字段?或者我应该存储'info_type'值?
我用Google搜索并没有发现任何东西=)
附:好的.我修改了'信息'类:
class Information(models.Model):
def save(self, *args, **kwargs):
self.info_type = self.fixed_info_type
super(Information, self).save(*args, **kwargs)

...并制作了几个代理人:
class InformationManager(models.Manager):
def __init__(self, info_type, *args, **kwargs):
self.__info_type = info_type
super(InformationManager, self).__init__(*args, **kwargs)
def get_query_set(self, *args, **kwargs):
return super(self.__class__, self).get_query_set(*args, **kwargs).filter(info_type=self.__info_type)
class PhoneInformation(Information):
fixed_info_type = 'PHONE'
objects = InformationManager(fixed_info_type)
class Meta:
proxy = True
class EmailInformation(Information):
fixed_info_type = 'EMAIL'
objects = InformationManager(fixed_info_type)
class Meta:
proxy = True

在admin.py中:
from contacts.models import Person, PhoneInformation, EmailInformation
class PersonAdmin(admin.ModelAdmin):
__inlines = []
class classproperty(property):
def __get__(self, instance, owner):
return super(self.__class__, self).fget.__get__(None, owner)()
@classproperty
@classmethod
def inlines(cls):
def get_inline(InformationModel):
class Inline(admin.TabularInline):
model = InformationModel
exclude= ['info_type']
return Inline
if not cls.__inlines:
for InformationModel in [PhoneInformation, EmailInformation]:
cls.__inlines.append(get_inline(InformationModel))
return cls.__inlines

所以它看起来很丑陋并且不符合DRY原则.我无法以与InlineAdmin相同的方式创建代理.它每次都会返回相同的对象.
